Roach, Chicago, Ill., assignor to Arvey lCorporation, Chicago, Ill., a corporation of Illinois r d .Application April-6, 1946, Serial No. 660,171 l'z claims, (c1. 248-495) This invention relates to improvements in a collapsible step display, and ismore particularly concerned with the provision of a step display embodying a single sheetof material adapted to be supported in step formation by means vof an easel secured to the back side thereofsaid sheetv and easel being collapsible to provide a flat, compact unit suitable for shipping or storage.

vThis invention further contemplates the provision of a step display in which the V sheet material is provided with a pair of paralleltransversely extending score lines, defining panel, step and riser portions which are movable relative to each other to their extended positions by pivotal movement of the easel supporting wing: outwardly from the plane of the sheet material to a position at right angles thereto.

This invention further contemplates the provision of a step display inwhichflthe easel is formed with a supporting tab disposed for pivotal movement against the underside of `Vthe step portion of the sheet material when the display is being arranged in its extended position.

This invention further contemplates the provision of a step display adapted tolbe supported in its extended position by means o'f'a single wing easel or a double wing easel. ,i A

This invention embodies other novel features, details of construction and arrangement of parts which are hereinafter set forth in. 4the specication and claims and illustrated in the accompanying drawings wherein: d

Fig. 1 is a side elevational-view showing a collapsible step display embodying featuresof this invention. p

Fig. 2 is a rear elevational view `of same.

Fig. 3 is a rear elevational view showing the display in its collapsed position.

Fig. 4 is a side elevational .view showing a modified form of collapsible stepldisplay in which the easel is provided with two vWing supporting portions.

Fig. 5 is a rear elevational view of same.

Fig. 6 is a rear elevational view showing the modied form of step display in collapsed position.

Referring now to the drawings for a better understanding of this invention and more particularly to Figs. l to 3 therein, a `step display is shown as comprising a sheet off material 8, such as cardboard, provided withparallel transversely extending score lines 9 and I I to dene a panel section I2, a step section I3" and a riser section I4. f

A single wing type of easel, generally indicated at I6, is formed from a sheet of cardboard to proiii vide a supporting wing Il having a top locking flap I8 hinged thereto along the score lines I9, the top locking flap being secured to the back side of the panel I2 by any suitable means, such as glue or staples, 2l. The sheet material I6 is out along the lines 22 and 23, and scored along the lines 24, 25 and 26 to form a bottom locking flap 2l, a spacing section 28, and a hinge section 29. The bottom locking flap 2l is secured to the back side of the riser section i4 by means of either glue or staples 3l. When the step display is in its extended position, it will be noted that the hinge section 29 isdisposed in vertical alignment with thetop locking ap I8, as illustrated in Fig. 1, and that the spacing section 28 is of proper width to dispose the riser section I4 in parallel alignment with the panel section I2.

The blank of sheet material I6 is also cut along the line 32 to provide a step supporting tongue 33 upon the wing portion I1. When the display is in its collapsed position, the step supporting tongue is disposed alongside the back face of the sheet material 8. When the display is moved to its extended position, the step 'Supporting tongue pivots inwardly about a hinge connection defined by the score lines I9 for supporting engagement under the bottom side of the step I 3. The sheet material I6 is also cut along the line 36 and scored along the line 31 to form a locking tongue 38 having a recess 39 formed therein to engage the edge 4I of the recess 42 to lock the display and its supporting wing I1 in extended position. The opening 42 extends outwardly at 43 to define a locking recess having an abutment shoulder 44 to limit downward pivotal movement of the locking tongue 38.

The step display is changed from its collapsed form, illustrated in Fig. 3, to its extended form, illustrated in Figs. l and 2, by pivoting the supporting wing I'I outwardly at right angles to its locking ilap I8, causing the step section I3 to pivot upwardly about the score line 9 and into supported position upon the step supporting tongue 33. During upward pivotal movement of the step section I3, the riser section I4 moves upwardly and outwardly into parallel alignment with lthe panel section I2. After the display is in its extended position, the locking tongue 38 is pivoted downwardly to engage the edge 4I of the supporting wing Il within the notch 39 to secure the step display in its extended position.

Figs. 4, 5 and 6 inthe drawings illustrate a modified form of collapsible step display provided with a double wing easel formed of a single sheet section I4 as heretofore described in connection if with the orm of invention illustrated in Figs. i, 2 and 3. The sheet material 46 is cut'transversely at 52 and 53 and cut axially at 54 to provide a pair of step supporting tongues 56-56 foi-:engagement under the step section I3 when the display is in its extended position, as illustrated in Figs. 4 and 5.

The sheet material 46 is also cut along the lines 51, 58-58, and 59-59, and scored at 6I and 62 to define a hinge section 63, a spacing section 64 and a bottom locking Vflap 66. The bottom locking flap 66 is secured to the riser section I4 by means of glue or Staples 6l.

A locking tongue 68 is formed on the sheet material .46 by means of a cut 69 and a score line 1I. The locking tongue is formed With recesses 72-1'2 for locking engagement with the supporting wings 49--49 when the display is in its extended position.

The double wing easel type display is collapsed to form a fiat, compact unit suitable for. shipping or storage by moving the locking tongue upwardly againstthe back face of the panel section I2, then pivoting the supporting wings 49--49 into engagement against the back of the panel section I2. This folding movement of the supporting .Wings causes the step supporting tongues--S to move from beneath the step section I3 to a plane parallel with the panel section I2; after which, the step section I3 and riser section I4 are free to move downwardly and inwardly into alignment with the panel section I2.

In each of the two forms of collapsible displays 'heretofore shown and described, it will be noted that each-form may be simply and inexpensively constructedv from two sheets of material, such as cardboard, to provide an attractive, sturdy structure when same is in its extended position, and vfurther to provide a ilat, compact unit suitable for shipping and storage when the display is in its collapsed position.

While this invention hasbeen shownin but vtwo forms, it is obvious to those skilled in the art vthat it is not so limited but is susceptible of various changes and modications without departing rom the spirit and scopeof the claimed invention.

I claim as my invention:
